Small-angle scattering data analysis for dense polydisperse systems: the FLAC program

Abstract FLAC is a program to calculate the small-angle neutron scattering intensity of highly packed polydisperse systems of neutral or charged hard spheres within the Percus–Yevick and the mean spherical approximation closures, respectively. The polydisperse system is defined by a size distribution function and the macro-particles have hard sphere radii which may differ from the size of their scattering cores. With FLAC, one can either simulate scattering intensities or fit experimental small angle ... Title of program: FLAC Catalogue Id: ADNF_v1_0 Nature of problem The problem is the calculation of the scattering cross section in small-angle scattering of polydisperse neutral and charged hard spheres. Both dense or dilute systems are considered. Versions of this program held in the CPC repository in Mendeley Data ADNF_v1_0; FLAC; 10.1016/S0010-4655(00)00202-2 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)摘要：FLAC是一款计算在Percus-Yevick和平均球形近似闭合条件下，高度堆积的多分散中性或带电硬球系统的中小角中子散射强度的程序。多分散系统由尺寸分布函数定义，宏观粒子具有的硬球半径可能与它们的散射核尺寸不同。使用FLAC，可以模拟散射强度或拟合实验中小角散射...
